I am not completely happy with it; the rhyme is halting, especially line 6 and 7, but still it was the best I could achieve..

I'd say that due to the meter, using a shorter synonym for "follow", *hil-/híla- seems practical here. (And defensible even if one wants to merely consider it a poetic word like nara-).

The shortest reconstruction for "to pursue, chase" would be either *ruida- or *ruia-, IMO.

Nice work.
Wouldn't 'with feet' be rather na dail?
'ertha na mên' > 'ertha na vên'?

Thanks! And well, quite possibly. I tried to use the preposition nan, and as far I can tell it causes nasal mutation and looses the final "-n" in the process. nan + tail --> na thail, and nan + mên --> na mên. But I certaily could have misunderstood things.

I see. The question is, is the definite article necessary there?

Shouldn't verain be verai from bara?

+Tamas Ferencz I did not think nan was a construct of de fenitite article, but justa prepostition on it's own, meaning "with". But if that is not the case, then no, I find S to be  filled with definite articles as it is without adding further. And I changed verain to verai.
+ܤܡܝ ܦܠܕܢܝܘܤ has híl- something to do with "heir", or were does it come from? Line 4-5
pe pelin boe de hílithon
na thail verai de ruiathon
this pacing might be better, yes. Thank you!
+ܤܡܝ ܦܠܕܢܝܘܤ An off-topic question, can your name be written with other symbols also? I am curious what your name is and I can't read the ones used in your signature. What letters are they?

+Hjalmar Holm My Google+ profile name is written in the Syriac Estrangelo consonant script — partly out of my preference to break patterns, partly thanks to the semi-anonymity it offers, partly because Tengwar wasn't available..

+ܤܡܝ ܦܠܕܢܝܘܤ  Then I call you Halvellon, hidden friend :-)

So híl- could mean either "follow" or "inherit"? I seems fine, the context could give the meaning, and in this case it is a quite strange thing to inherit the road versus follow it.
